On your first visit a scratch test and/or an intradermal skin testing series may have to be done to ascertain your allergies to: dust, grasses, trees, animal dander, etc. The sensation felt on testing is comparable to a mosquito sting or a pinprick. We then look for a reaction on the skin after 15 minutes, observing any evidence of redness, hives or itching. For patient safety, testing may need to be completed in multiple visits. If you react strongly to any of the antigens, we may have to do less testing per visit, which would prolong the length of time to finish testing.
It is absolutely necessary that all antihistamines, and any medication containing antihistamine, be discontinued 48 hours prior to your appointment. Examples: Allegra, Benadryl, Clarinex, Claritin, Tylenol Pm, Xyxal, Zyrtec, etc. You should continue to take any medication prescribed by other physicians for asthma, blood pressure, diabetes, heart trouble, etc. At the completion of all tests, a further consultation will be held with the provider at which time all aspects of your condition will be discussed. Your initial visit will take anywhere from 45 to 90 minutes.
